Studies in anthraquinone: Preparation of 2-substituted pyrimidoanthraquinones and related fused 1,2,4-triazolo, tetrazolo and pyrazolino derivatives

This paper describes the synthesis of 2-substituted-4(3H)- oxopyrimido[4,5-α]anthraquinone, 2-substituted-4-hydrazinopyrimido[4,5- α]anthraquinones, several 2-substituted-1,2,4-triazolo[4,3-c]pyrimido[4,5- α]-anthraquinones tetrazolo[4,5-c]pyrimido[4,5-α]anthraquinones and pyrazolinopyrimidoanthraquinone derivatives.
